Sorry, I didn't notice corp proxy in the link. Here are publicly available patches:
- [glibc-syscall.h move](https://android-review.googlesource.com/c/platform/bionic/+/221800)
- [sys/io.h](https://android-review.googlesource.com/c/platform/bionic/+/3135242)
> Android is not mentioned anywhere. It is truly undocumented feature, so I think it's fine to update it.

I'll add this to my list once flashrom is fully accepted as Android external tool (It shouldn't take long) :)
> I was thinking to put that "minimum version number" in some doc, but there is no such doc.

C23 has __has_include, but I doubt flashrom will switch to C23 soon to incorporate this. I'll look for ways to check Android version in C #if, so we can cover all major cases with sys/io.h

I added testing description. I cannot provide links right now, as flashrom didn't pass Android review yet and thus its mirror is not available in AOSP yet, but I can assure you it works on the latest branch.
